There's a war going on in Paris, and despite the lessons we've learned from video games that war never changes, this is the first war I'm aware of that is being waged with Post-It Notes. On one side is Ubisoft's Paris HQ. And the other is French bank called BNP, each trying to one-up the other with video-game characters turned into Post-It Notes.

This fracas started back in May, according to a Ubisoft spokesperson. "A gal in our Paris office decided to decorate her windows back in May and made a post-it image from Space Invaders. One or two other people there thought that was cool, so they did some images as well. It took a few weeks but apparently someone from the BNP Paribas headquarters (a bank) across the street is a video game fan so he did one of his own. And thus the war began."

I asked Ubisoft what will make this war stop. "No idea," a company rep said. "We're letting the team run with it and it will end whenever it ends. Or, maybe when we run out of windows! However, some of the original designs have already been taken down to make way for newer better ones."

If you're in Paris and are seeing more signs of the ongoing #postitwar, please post them here. It appears that this site is running a lot of the resulting PostIt War and the ancillary skirmishes that followed, but my French is awful, so I"m not 100% sure.
